Photorespiratory Bypass

Rubisco is the main enzyme that is responsible for capturing carbon dioxide and turning it into sugars for the plant. Turns out, that while Rubisco is one of the most vital components of photosynthesis—it’s not very good at its job in most crops such as cowpeas, soybeans, and rice. About 35 percent of the time, Rubisco tries to fix oxygen instead of carbon dioxide. This error produces a carbon compound called glycolate that the plant must recycle to salvage a portion of carbon that can be used in photosynthesis. This recovery process, however, costs the plant a large amount of energy. The RIPE team has created a shorter recovery pathway, conserving energy and resources that the plant can reinvest to increase crop productivity by as much as 40 percent, according to work published in Science in 2019. Right now our team is translating these findings to key food crops including potatoes and soybean.

The underappreciated role of pods and siliques to developing seeds

Research overseen by RIPE's Doug Allen discovered that plant pods support seed development and higher yields, playing a significant role in photosynthesis. Their work was recently published in Science Advances.

Researchers improve seed nitrogen content by reducing plant chlorophyll levels

Chlorophyll plays a pivotal role in photosynthesis, but it uses a lot of a plant's resources. RIPE researchers wondered if they reduced a plant's chlorophyll levels, if the plant would invest those resources in other areas, potentially improving nutritional quality or yield. Their findings were recently published in the Plant, Cell & Environment journal.

The heat is on: RIPE researchers show ability to future-proof crops for changing climate

Research from Illinois and the USDA-ARS show that bypassing a photosynthetic glitch common to crops like soybean, rice, and wheat, can confer thermal protection under heat stress in the field.
